Abstract
The invention relates to a corrosion-resistant axial ball bearing which comprises an annular retainer, balls and thrust washers, wherein a plurality of circular holes are uniformly formed along the circumference of the annular retainer, the balls are embedded into the circular holes, the thrust washers are respectively located on both sides of the annular retainer, ball grooves are formed along the circumference of the thrust washers, and the surfaces of the ball bodies of the balls exposed out of the circular holes are embedded into the ball grooves. The annular retainer is made from one of silicon carbide, silicon nitride and a high molecular composite material, the balls are made from a pressure sintered silicon nitride material, and the thrust washers are made from of one of silicon nitride and silicon carbide materials. The wear resistance and corrosion resistance of the axial ball bearing prepared from the materials are greatly improved, so that the axial ball bearing is applicable to machines in industries such as foods, petroleum, printing and dyeing, medicines, chemical industry and electroplating for conveying liquids such as petroleum and chemical liquids with corrosion resisting, high temperature resisting and high pressure resisting demands.
Description
Technical field
The present invention relates to a kind of axial ball bearing, particularly a kind of corrosion resistant axial ball bearing.
Background technique
Along with the development of bearing industry, in order to meet different needs, there is various bearing, but the machinery of the liquid such as transfer oil and chemical mediator for industries such as food processing, oil, printing and dyeing, medicine, chemical industry, plating, corrosion-resistant to it, high temperature resistant, high voltage bearing characteristic requirements is higher, but the general corrosion resistance of existing bearing is poor, can not meet the requirement of manufacturing machine.
Summary of the invention
In order to solve the problem that above-mentioned prior art is difficult to overcome, the invention provides a kind of corrosion-resistant axial ball bearing.
Comprise annular retainer 1, ball 3, thrust washer 4, described annular retainer 1 circumferentially evenly has multiple circular hole 2, the number of circular hole 2 is at least 3, the number of circular hole 2 can adjust according to the diameter of the thickness of thrust washer 4 and ball 3, and described ball 3 embeds in circular hole 2, and the diameter of ball 2 should be greater than annular retainer 1 width.
Two of feature of the present invention is: described thrust washer 4 lays respectively at the both sides of annular retainer 1.Described thrust washer 4 is circumferentially provided with ball grooves 5, and the spherome surface that described ball 2 exposes to the circular hole 2 of annular retainer 1 embeds in ball grooves 5, and the degree of depth of described ball grooves 5 and the width sum of annular retainer 1 are less than the diameter of ball 3.
Three of feature of the present invention is: described annular retainer 1 the selection of material is the one in silicon carbide, silicon nitride and composite high-molecular material.
Four of feature of the present invention is: described thrust washer 4 the selection of material is the one of silicon carbide and silicon nitride material.
Five of feature of the present invention is: described ball 3 is gas Pressure Sintered Silicon Nitride ball.
The invention has the beneficial effects as follows: the axial ball bearing made with above-mentioned material is wear-resisting, corrosion resistance is obtained for very large raising, is applicable in the machineries of industry in order to corrosion-resistant, high temperature resistant, the high pressure resistant requirement of having of the liquid such as transfer oil and chemical mediator such as food, oil, printing and dyeing, medicine, chemical industry, plating.
